Abstract:
The present invention provides an image processor capable of preventing illegal copying of a document. The image processor first extracts information from a barcode in a first region of document image data. Then, the image processor extracts information from a barcode in a second region of the document image data if the information is extracted from the barcode in the first region. On the other hand, if the information is not extracted from the barcode in the first region, the image processor does not extract the information from the barcode in the second region of the document image data. This enables a copying operation for a document consisting of a plurality of pages to be efficiently controlled.
